Objectives: 1. Students can describe the different types of
interactions within an ecosystem. 2. Students describe symbiotic relationships in
which one or more species benefits. 3. Students will be able to describe symbiotic
relationships in which one species is harmed.

Predator and PreyMany interactions in an ecosystem
involve food.A predator is an animal that eats another
animal.The prey is the animal that is eaten by the
predator.Organisms can be both predator and
prey

Competition
Competition is the struggle between individuals of different populations for limited resources.
Competition may occur between the same species
Ex. – Wolves compete over territory Competition may also occur between different
species. Ex.- Vultures and Hyenas compete over animal
remains. Organisms may compete over food, living
spaces, water, and mates

Cooperation Cooperation is an interaction between two
or more organisms that are working together.
Organisms will use cooperation when hunting or taking care of their young.

Symbiosis
Symbiosis is the interaction between two individuals from two different species that live closely together.
There are three types of symbiosis1. Mutualism2. Commensalism3. Parasitism

Mutualism Mutualism is the interaction between two species
that benefits both. Ex. – Bees obtain nectar (food) from flowers and
the flowers get pollen

Commensalism Commensalism is the relationship
between two species in which one benefits while the other is not affected.

PARASITISM
Parasitism is a relationship between two species in which one benefits and the other is harmed.
They will live on or inside of their host Parasites are often tiny creatures Ex. – Ticks, lice, mites, mosquitoes Parasites cause harm to their host, but
usually do not kill their host.

Ecosystem Interactions Are Complex Symbiosis is one of many interaction that
take place in an ecosystem An ecosystem is much more than a
collection of biotic and abiotic factors. These interactions help explain how
resources are shared and used up and how energy flows through the ecosystem.
